To make a glass, there are some steps to follow. First of all, you have to get all of the ingredients and tools: sand, soda, limestone, furnace, roller and removable mould. Then the sand, soda and limestone are mixed and heated in the furnace. After about a day, separate this mixture into two: the first part is flowed to a roller and the second is flowed to a bottle-shaped mould. Finally, after those are cooled, the first part becomes a plate glass and the second becomes bottle glass (after the mould is removed).
